Lenovo u41-70 cpu at 0.48GHz throttle issue when battery below 30%

Hi,

 

I have a lenovo U41-70 with i75500U cpu.

I notice an issue wuth the cpu speed when on battery.

When the battery charge goes below 30% the cpu speed drop to 0.48GHz constantly.

Cpu speed return to a normal behaviour as soon as I plug in.

I saw this same issue on different posts and for different laptops but did not see a proper fix for it.

As it seems to be a bios issue I upgraded the bios driver from BDCN28WW to BDCN71WW but it did not help.

Also I run Lenovo system update and update al the drivers.

 

I also checked the battery advanced setting but did not see anything related to the issue.

Why Lenovo does not provide a solution for this issue?

 

Does anybody found a solution for this?

Thanks.
